So_mi I took a hiatus during my entire last college semester and part of the summer before. Life had took an unexpected turn, so writing happened to fall to the side among other things. Granted, I wasn't in the best health ever, but I didn't want to hurt myself more (because of time and responsibility constraints) to write. Thankfully, my readers were understanding, and I didn't lose much (if any really).
I think if I had forced myself to write, it wouldn't have done myself or my story an good. In fact, now that I'm back, I have a renewed energy and determination to continue. So having a break can actually be the best motivation instead of trying to force motivation out. Because then, as others said, it becomes a chore, which is the least ideal for creativity. So relax, unwind, pig out, do whatever the hell you feel like, and when the times comes, your mindset will be more than enough ready to tackle writing again.
Best of luck to you! Have a good life and New Year!
